TST Power Kit without Video

320 horsepower and 920 torque are the maximum numbers EPA certified on these engines.

These kits do not work on the ’97 and later 300 or higher horsepower mechanical engines.  TST has no power enhancements for the ISC electronic controlled 8.3 engine.

The Power Kit can normally be installed by a first-timer in about two hours, while a couple minutes a day for the next week might be required to tweak in the best smoke settings.

Gauges are very helpful in troubleshooting and are highly recommended if you add above 75 hp.  TST has a 60 psi boost gauge kit for $50 and a 1500 degree F exhaust pyrometer kit for $150.  Add $50 for tubing and wiring on rear engine motorhomes.  These kits contain all tubing, fittings, wiring, and sensors.  These prices do not include gauge mounting cups which we offer for $35 per gauge.

Exhaust temperatures are normally safe with all but the highest power kit; however radiator temperatures may be a problem if the loads you pull use full power for long periods of time. TST has dyno tested many aftermarket items such as low restriction air filters and mufflers, larger exhaust systems, and has found nothing that significantly reduces exhaust manifold or piston temperatures.
